What are the stages involved in both mitosis and meiosis?
Both mitosis and meiosis involve prophase, metaphase, anaphase, and telophase as part of their processes.
Why is meiosis important for reproduction?
Meiosis produces gametes with half the chromosome number of parent cells, essential for sexual reproduction and ensuring genetic variation in offspring.
How does meiosis contribute to genetic diversity?
Meiosis introduces genetic diversity through processes like crossing over and independent assortment during the formation of gametes.
What is the main purpose of mitosis?
Mitosis serves to grow and repair tissues by producing two identical daughter cells from a single parent cell.
Can mitosis occur in all types of cells?
Mitosis occurs in most eukaryotic cells except for sex cells which undergo meiosis to produce gametes.
What can go wrong during mitosis?
Errors during mitosis can lead to conditions such as cancer if cells divide uncontrollably, or genetic disorders if chromosomes are not distributed correctly.
What are the main differences between mitosis and meiosis?
Mitosis results in two genetically identical daughter cells with the same number of chromosomes as the parent cell, while meiosis produces four genetically unique cells with half the number of chromosomes, contributing to sexual reproduction.
How do cells ensure that each daughter cell gets the correct number of chromosomes?
Cells use spindle fibers to align and pull apart chromosomes during mitosis, ensuring each daughter cell receives an identical set of chromosomes.
What triggers the start of mitosis?
Mitosis begins following the completion of the G2 phase of interphase, triggered by specific genetic and molecular signals that ensure the cell is ready to divide.
Is the greenhouse effect harmful?
While naturally beneficial, an enhanced greenhouse effect due to human activity is harmful as it leads to global warming and climate change.
